Subtitles 1.20.0

• Copy a box's text. A Copy button shows at the top end of the box
  while the pointer is over it and the box takes clicks: with ⇧ or ⌥
  held, or with Pointer Reveal and Click-Through off. One click puts the
  box's text on the clipboard, with the other language under it when both
  are shown, and the button says Copied. The words around it fade out so
  it stands clear of them, and with a name tab it sits level with the tab
  instead.
• Copy from the ⌥ stack. Each box in the stack shows the same button
  while the pointer is over it.
• The search pill brightens. Under the pointer, the ⌥F search pill's
  symbol, placeholder and hint come up a step, as the Copy button's
  symbol and word do.
